To allwhom it may coacern V Be it known that 1, Lee I. STEVENS, a citizen of the United States, residing at Denver, in the county of Denver and State of Col rado, have invented certain new and useaul Improvements in Machines for Crimping Pail-Covers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in machines for crimping covers on pails or cans, and an object of this invention is the provision of a portable crimping machine which maybe easily and quickly operated by one person.

Another object of this invention is the provision of a-machine of this character which comprises a shaft upon which a cover engaging plate or chuck is loosely mounted, a sleeve being keyed upon the shaft above the plate, the sleeve carrying a pair of crimping disks which are adapted for engagement against the periphery of the pail,

means being providedto force the disks against the pail and to move the same in an are, so that the disks form a crimp in the cover to seal the same to the pail.

A still further object of this invention is the provision of acrimping device of this character which comprises a cover engaging plate in which the lower end of a shaft is rotatably mounted, the shaft having a sleeve keyed thereon above the plate, from which a pair of oppositely extending arms pro ect, the outer ends of the arms projecting beyond the edge of the plate and having rocking levers pivotally connected thereto, the lower ends of the rocking levers carrying crimping disks for engagement against the periphery of the can, means being provided to force the upper ends of the rocking levers outwardly whereby the crimping disks are moved inwardly against the can, as the plate is forced downwardly against the cover'of the can.

With these and other objects in view, my invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which- Figure 1 is an elevational view of my improved device; Fig. 2 is a sectional view on the line 2-2 of Fig. 1; Fig. 3 is a sectional view on the line 3 -3 of Fig. 1; Fig.

iris a sectional view on the lined-'45 of Fig v 1; F i g. 5 is a sectional view on the line 55 of Fig, l; Fig. 6 is a fragmentary vertical sectional view showing the manner of forcing the operating rods outwardly to move the crimping disks inwardly toward the plate.

Referring more particularly to the drawing, the numeral 1 designates a cylindrical shaft in which is formed adjacent its lower end an annular groove 2, a cover engaging plate or chuck 3 being mounted on the lower end of the shaft,'the plate having a threaded opening therein through which a set screw 4 is passed, the inner end of the set screw engaging in the annular groove 2 in the shaft, whereby the lower'end of the shaft is rotatably mounted in the plate. Keyed on the shaft immediately above the plate is a sleeve 5, and extending radially from the opposite sides of said sleeve are arms 6, the

outer ends of which project beyond the edge of the plate 3. Pivotally mounted intermediate of their ends upon the outer ends of the arms 6 are rocking levers 7, the lower ends of which are reduced and threaded asat 8 for the reception of crimping disks 9,

the disks being maintained in position upon the lower ends of the rocking shafts by suitable nuts 10. Formed in the upper face of the'sleeve 5 is a tapered seat or recess 11 and formed in the wall of the sleeve at diametrically opposite points are openings 12 which communicate at their inner ends with the recess l1. Piv'otally connected to the upper ends of the rocking levers 7 are operating rods 13, the inner ends of which extend through the openings 12 in the sleeve within the recess 11, the inner extremities of the rods being beveled as at 14.

Mounted on the upper end of the shaft is a handle 15, the portion of the handle engaging the shaft having vertically extending elongated slots .16 formed therein, the shaft having 'a pin '17 extending therethrough, the opposite ends of which engage in the slots 16, whereby the handle is slidably mounted upon the shaft and rotatably carried thereby. Depending from the handle and extending around the shaft is a collar 18, the lower extremity of which is tapered as at 19 for engagement in the tapered recess 11 in the sleeve 5. The device is carried from place to place by the handle 15, the pin 17 engaging the lower ends of the slots, whereby the tapered portion 19 of the collar is withdrawn from the Him the sleeve,

I of the plate 3.

In the practical use of my improved device, the device is supported by the handle 15, and the plate 3 is engaged against the cover of the pail after same has been placed over the open end of the pail, the

opposite ends of the pin 1? being disposed in the lower end of the slots 16, so that the disks 9 are arranged outwardly of the periphery of the pail on opposite sides thereof. When the device is in this position, the inner beveled ends of the operating rods 13 project within the recess 11 in the sleeve, and upon forcing the handle downwardly, the tapered lower end 19 of the collar carried by the handle is moved into the recess 11, to force the rods outwardly to rock the levers 7, whereby the disks 9 are moved inwardly to tightly engage against the flange of the cap and form a crimp in the flange and in the wall of the can or pail. The handle is then turned, by means of which the shaft 1 is rotated whichcarries the disks in an are around the pail and forms a crimp in. the. cover and in the pail entirely around the same. It will be readily understood that plates 3 may be made in various diameters, the several plates being readily interchangeable by reason of the set screw 4:, so that the plate of the desired diameter may be mounted upon the lower end of the shaft to engage the covers of various sizes of pails. To normally draw the operating rods 13 inwardly, contractile springs 20 are provided, the in ner ends of the springs being connected tothe sleeve 5, and the outer ends of the springs being connected to the rods 13, whereby the crimping disks 9 are normally maintained in spaced relation from the edge of a plate 3.

From the above. description taken in connection with the accompanying drawing, it

will be seen that I have. provided a machine for crimping covers upon pails, which may be readily operated by one person, and which may be quickly removed from one pail after the same has been operated upon and connected to another pail, the machine being extremely light and simple in construction, so that the same may be cheaply manufactured. I

Having thus fully described my invention what I desire to claim and secure by Letters Patent, is

1. A device of the character described ender of this patent may as obtained as comprising a shaft, a plate loosely mounted upon the lower end of the shaft, a sleeve keyedupon the shaft above said plate, arms extending radially from said sleeve and having t ieir outer ends projecting beyond the edge, f said plate at diametrically opposite points thereof, sizing levers pivotally connected interme date of their ends to the outer ends of said arms, rotatable crimping disks carried by the lower ends of said rocking levers, a pin disposed through said shaft at its upper end and having its opposite ends projecting from said shaft, a handle mounted upon said shaft and having slots therein to receive the opposite ends of said pin whereby the shaft is rotated by the handie and the handle is slidable thereon, and means carried by said handle for actuating said rocking levers to move the crimping disks inwardly toward the plate.

2. A device of the character described comprising a shaft, a plate loosely mounted upon the lower end of the shaft, a sleeve keyed upon the shaft above the plate, arms extending radially from said sleeve and having their opposite ends projecting beyond the edge of said plate, rocking levers pivotally connected intermediate of their ends to the outer ends of said arms, crimping disks rotatably mounted upon the lower ends of saidroclring levers outwardly of the edge of said plate, the upper face of said sleeve having a tapered recess therein, openings formed in the sleeve at diametrically 0pposite points and communicating with said recess, operating rods pivotally connected at their outer ends to'the upper ends of said rocking levers, the inner ends of said arms extending through said openings and norcarried by said shaft above the sleeve for mally projecting within the recess, handle rotating the shaft, said handle being slidably mounted upon the shaft and having a tapered extension at its lower end for engagement in-the tapered recess in the sleeve,

whereby the operating rods are moved out-' LEO l. STEVENS.
